[None][fix] Isolate modeling_v2 tests and scope shared test state - #21345
Modeling_v2 tests can leave process-wide environment and TF32 settings changed for later tests. Qwen also executes other pytest modules to reuse operands, creating separate heavyweight caches. Model-owned tests at the unit root or outside the modeling_v2 tree weaken family-specific CI selection.
Scope accuracy-test environment overrides per engine and restore the previous values after shutdown or failure. Keep the precision context manager in test helpers and scope test-side reference calculations; op definitions retain their original behavior.
Share FP4 operand helpers through ordinary imports and release large reference caches at module teardown.
Move 11 model-specific root files and six K3 speculative test files into their family directories; update CPU test lists. Preserve all 153 moved source test functions, cells and numerical tolerances.
Recognize parenthesized target imports in CBTS so Kimi changes retain family selection.
Remove the README's absolute no-model-import-on-decline statement.
Test Coverage
53 targeted environment, helper-lifetime and CBTS pytest cases passed together, including selection against the repository's CPU test list for all five families.
24 precision-scope/source cases passed with the test helper loaded using a stubbed torch import; two real-PyTorch backend cases were not run.
All applicable pre-commit and commit-message hooks passed, including DCO, vendored-source checks and AST test-list validation.
Ruff lint/format, Python compilation and the existing source-level CI-enrollment check passed.
GPU numerical tests and E2E accuracy evaluations were not run: the local environment lacks a matching PyTorch/TRT-LLM runtime.
K3 routing and the best-effort import-isolation guard are unchanged.
PR Checklist
Reviewed the applicable checklist items; no public API or dependency changes.
Dev Engineer Review
The change scopes modeling-v2 environment overrides to each LLM lifetime and restores affected keys when the scope exits. It scopes reference matmuls to IEEE FP32 without changing process-wide TF32 policy. Shared FP4 helpers replace dynamic test-module imports, and fixtures release reference layers and geometry caches at teardown.
The CBTS rule now recognizes parenthesized target imports. The README removes the claim that a declined route avoids importing modeling code. K3 routing and the best-effort import-isolation guard are reported as unchanged.
No current review findings were supplied, so severity counts are unavailable.
QA Engineer Review
The change adds CPU-only tests for environment restoration, precision scoping, FP4 helper imports and fixture cleanup, and parenthesized-import CBTS selection. It modifies modeling-v2 accuracy and MoE tests, moves model-specific tests into family directories, and updates the CPU test list. The supplied summary reports that the 153 moved source test functions, cells, and numerical tolerances are preserved.
The supplied results report that 53 targeted environment, helper-lifetime, and CBTS pytest cases passed together. They also report that 24 precision-scope and source cases passed with a stubbed torch import. Applicable hooks, Ruff lint and format, Python compilation, and a source-level CI-enrollment check passed. Two real-PyTorch backend cases, GPU numerical tests, and E2E accuracy evaluations were not run. Coverage verdict: needs follow-up because those runtime checks remain unverified.
tests/integration/test_lists/test-db/l0_cpu.yml adds or updates CPU test entries. The supplied summary does not establish whether changed integration accuracy tests appear in CI or manual-QA lists.

The PR updates accuracy-gate matching for parenthesized imports, scopes test environment and FP32 precision settings, consolidates NVFP4 MoE test utilities, and revises test registration and import paths.
Changes
Accuracy-gate target matching
Layer / File(s)
Summary
Match target imports jenkins/scripts/cbts/cbts/rules/modeling_v2.py, tests/unittest/scripts/cbts/test_modeling_v2.py, tensorrt_llm/_torch/_experimental/modeling_v2/README.md
The gate rule recognizes plain and parenthesized target-class imports. Tests cover family-specific gate selection. The README no longer claims that a declined route avoids loading modeling code.
Scoped modeling-v2 test environments
Layer / File(s)
Summary
Implement and test environment restoration tests/integration/defs/accuracy/modeling_v2/_env.py, tests/unittest/_torch/modeling_v2/test_modeling_v2_env_scope.py
scoped_env_overrides restores overridden keys or removes keys that were initially absent. CPU-only tests cover nested scopes, failures, environment changes, and scoped use around accuracy-test LLM calls.
Use scoped overrides in accuracy tests tests/integration/defs/accuracy/modeling_v2/test_{deepseek_v3,glm_moe_dsa,gpt_oss,kimi_k3_vl,qwen4_exp}.py
The listed accuracy tests apply environment overrides through scoped_env_overrides around LLM construction and use. Qwen4-Exp tests continue to require modeling-v2.
Reference matmul precision
Layer / File(s)
Summary
Define and test the precision scope tests/unittest/_torch/modeling_v2/_precision.py, tests/unittest/_torch/modeling_v2/test_modeling_v2_reference_precision.py
true_fp32_matmul sets CUDA matmul precision to ieee and restores the prior setting. Tests cover nested scopes, exceptions, decorated calls, and backend restoration.
Apply true FP32 to MoE references tests/unittest/_torch/modeling_v2/models/deepseek_v3/..., tests/unittest/_torch/modeling_v2/moe/test_modeling_v2_*moe_runner.py
Selected MoE reference calculations now run inside true_fp32_matmul. The changes remove module-level TF32 overrides.
FP4 MoE test support
Layer / File(s)
Summary
Build shared FP4 operands and references tests/unittest/_torch/modeling_v2/_fp4_moe_test_utils.py
Shared helpers generate and transform NVFP4 operands, build reference MoE outputs and routing inputs, compare results, and provide a lazy many-expert fixture.
Use shared helpers in MoE tests tests/unittest/_torch/modeling_v2/moe/test_modeling_v2_fp4_block_scale_moe_runner.py, tests/unittest/_torch/modeling_v2/models/qwen4_exp/qwen3_8_flash_next_nvfp4__sm_103__tp1/moe/*
The tests use shared operand and fixture helpers instead of local implementations or dynamic test-module loading. Cute DSL tests prepare expert weights and scales in a fixture.
Test helper loading and cleanup tests/unittest/_torch/modeling_v2/test_modeling_v2_fp4_test_helpers.py
CPU-only tests check helper imports, lazy fixture construction, independent fixture instances, and cleanup after normal and failed test execution.
Test registration and import paths
Layer / File(s)
Summary
Update test registration and import roots tests/integration/test_lists/test-db/l0_cpu.yml, tests/unittest/_torch/modeling_v2/models/deepseek_v3/test_modeling_v2_deepseek_weight_table.py, tests/unittest/_torch/modeling_v2/models/gpt_oss/test_modeling_v2_weight_table.py, tests/unittest/_torch/modeling_v2/models/qwen4_exp/test_modeling_v2_qwen4_exp_*.py
The CPU test list adds entries and moves model-specific entries into model directories. DeepSeek, GPT-OSS, and Qwen4-Exp test import hooks use updated relative paths.
This change isolates modeling_v2 test state and reorganizes tests; it does not change production behavior. A few test-coverage gaps should be fixed. The CBTS regression tests may be skipped in the CPU lane. Two guards can pass despite regressions they are meant to catch. The matmul precision restoration may leave a different setting than the caller had. These are bounded and should be fixed or accepted before merge.

Test the precision policy inside each MoE reference.
The precision test decorates a dummy function. It does not check that this reference, the MXE reference, or FusedMoe.reference enters the scope. Their existing comparisons can pass with the default IEEE policy even if a decorator is removed.
Add a small case to each corresponding MoE test that starts with tf32, observes ieee during the reference, and checks restoration afterward.
As per path instructions: “For each new or materially changed observable behavior,” identify a meaningful test.

Preserve the inherited matmul policy.
PyTorch 2.14 returns the effective precision here, not whether the matmul setting inherits it. If the global policy is tf32 and matmul is "none", this scope restores an explicit tf32. A later global change to ieee then leaves matmuls at tf32. This can change later computations in the process. Preserve the inheritance state, or isolate the reference when PyTorch cannot expose it. Add a regression test that changes the global policy after the scope. (raw.githubusercontent.com)

Mark the CBTS test module for the CPU lane.
When the run uses -m cpu_only, tests/unittest/conftest.py skips a file whose text lacks pytest.mark.cpu_only. test_modeling_v2.py has no such marker, so the two new regression tests and the file's existing tests are not collected in the CPU lane, even though l0_cpu.yml lists unittest/scripts. Add a module-level marker, as the sibling cbts test modules do.

Check precision assignments in production references.
This assertion rejects true_fp32_matmul by name, but it accepts a reference that directly assigns torch.backends.cuda.matmul.fp32_precision.

Require env_overrides= or ** unpacking on each scoped LLM(...) call.
The AST guard in test_accuracy_engines_are_inside_environment_scopes checks only that each LLM(...) call sits in a with block that also enters scoped_env_overrides(...). It does not check the call's keywords. A call that drops env_overrides= still passes. The helper's docstring says the yielded mapping must reach LLM(env_overrides=...) so that rank workers receive the variables. The guard does not check that path.
Add a keyword check after the existing scope assertion. It accepts env_overrides= and ** unpacking, which are the forms used by the current accuracy engines.
Proposed check
assert set(calls) <= scoped, (
f"{source.name} constructs LLM outside an environment scope at lines "
f"{sorted(call.lineno for call in set(calls) - scoped)}"
)
+ undelivered = [+ call.lineno+ for call in calls+ if not any(keyword.arg in ("env_overrides", None) for keyword in call.keywords)+ ]+ assert not undelivered, (+ f"{source.name} builds LLM without env_overrides or ** kwargs at lines {undelivered}"+ )

Description
Modeling_v2 tests can leave process-wide environment and TF32 settings changed for later tests. Qwen also executes other pytest modules to reuse operands, creating separate heavyweight caches. Model-owned tests at the unit root or outside the modeling_v2 tree weaken family-specific CI selection.
Test Coverage
K3 routing and the best-effort import-isolation guard are unchanged.
PR Checklist
Dev Engineer Review
The change scopes modeling-v2 environment overrides to each
LLMlifetime and restores affected keys when the scope exits. It scopes reference matmuls to IEEE FP32 without changing process-wide TF32 policy. Shared FP4 helpers replace dynamic test-module imports, and fixtures release reference layers and geometry caches at teardown.The CBTS rule now recognizes parenthesized target imports. The README removes the claim that a declined route avoids importing modeling code. K3 routing and the best-effort import-isolation guard are reported as unchanged.
No current review findings were supplied, so severity counts are unavailable.
QA Engineer Review
The change adds CPU-only tests for environment restoration, precision scoping, FP4 helper imports and fixture cleanup, and parenthesized-import CBTS selection. It modifies modeling-v2 accuracy and MoE tests, moves model-specific tests into family directories, and updates the CPU test list. The supplied summary reports that the 153 moved source test functions, cells, and numerical tolerances are preserved.
The supplied results report that 53 targeted environment, helper-lifetime, and CBTS pytest cases passed together. They also report that 24 precision-scope and source cases passed with a stubbed torch import. Applicable hooks, Ruff lint and format, Python compilation, and a source-level CI-enrollment check passed. Two real-PyTorch backend cases, GPU numerical tests, and E2E accuracy evaluations were not run. Coverage verdict: needs follow-up because those runtime checks remain unverified.
